I just think Rich is going to be difficult to deal with for a while - since he didn't choose to split, he is going to be acting irrationally for a while. I hope that it doesn't get too difficult or ugly, and I really hope he can stop drinking. I'm sorry - I've never really had to break up with someone who I then had to remain close with (kids or other shared responsibility) so I can't imagine how hard it is.
